Chapter 5: Sister Act, act I
You look at your gorgeous sister, so turned on you can't even think straight. Tracy works out a lot, and she has a lean, firm body, with incredible DD-cup breasts. She's a brunette, and has a deep solarium tan without the slightest hint of tan-lines.You're overcome with lust, and only manage to moan out,
"God, I want you, Tracy. I want you so bad!"
In response Tracy undoes her bikini top, showing all of her firm and perfectly formed breasts, and then pulls off her bikini bottom, exposing a completely shaved pussy, just as tanned as the rest of her.
"So, my little sister is bi", she says. "You like what you see?"
"God, yes! I wish I had a body like yours!"
"Your breasts are larger than mine were at your age. You're gorgeous already."
Tracy takes a swimming stroke, gliding over to you. All you manage to stutter out is:
"I- I've never been with a girl. I don't know what to do!"
"Leave that to me, Lisa", Tracy tells you. She pulls the two of you out of the water, while undressing you completely. She kisses you deeply, and you respond with a passion you didn't know you had in you. Tracy lays you on your back, and works her mouth down your body, licking your neck and breasts, tracing the outlines of your stomach with her tongue. When she reaches your pussy, with its soft, blond fuzz, she teasingly works around it, licking your inner thighs before almost painfully slowly nearing your clitoris. You're so tense you can hardly breathe.
Finally, her tongue reaches your clit. The very first touch is like pushing a button, releasing months of sexual tension. You orgasm hard, screaming untrollably, and your orgams just goes on and on while Tracy laps at your clit and pushes two fingers into your tight, tight slit. Finally, after what feels like an eternity, you come down from your sexual high.
Tracy looks up at you, smiling. "You really did need it, sis. I've never seen anyone cum so hard."
"I love you, Tracy!" you exclaim. "I've never felt anything like that! Please, let me do you next!"
Tracy spreads her legs, exposing her beautiful, shaved pussy. "Go ahead, Lisa."
You dive in between her legs, thinking of nothing but repaying her for the incredible pleasure she gave you. You're uncertain at first, but you quickly learn what Tracy likes, and you lick her juices with abandon. The feel of your tongue against your sister's clean-shaven cunt is incredible, and you decide to shave your own pussy as soon as possible. After a few minutes, Tracy begins to breathe heavily, moaning in pleasure. You insert three fingers into her pussy, and you're surprised at the tightness of her cunt, considering how much use she puts it to. You wouldn't call your sister a slut, but you know she has had scores of lovers since she lost her virginity. You shudder for a moment as you recall she told you it was your brother Johnny who took her cherry.
You fingerfuck her pussy while you lick and suck at her clitoris, and soon she orgasms, screaming in pleasure and spewing her juices over your face.
"Well done, Lisa", she tells you when she has calmed down. I could turn you into a real expert at this. But right now, I want you to make a choice." Tracy crawls over to a bag she kept by her towel. "I thought I would be by myself here, so I brought a few toys. Do you want us to keep this soft and loving, or would you like it really hard?"
You answer,
